What does a auto repair shop need in Ada County that other businesses do not?
1 of the 1 permit particular to a auto repair shop here applies to no other business type we cover in Ada County: Automotive Repair Shop License — Idaho state position.

A repair shop needs only the ordinary registrations that apply to any Idaho business, such as the sales tax permit above if it sells parts.
The other 4 local permits in the tables apply to every type of business in Ada County, ID; what each one involves is set out on the Ada County permits page. The 5 state-level registrations apply to every type of business across ID and are covered on the ID state page.
